COMBINED DlSCOUNI-MEASURING GLASS AND BANK-NOTE EXAMINER.

SPECIFICATION forming part of Letters Patent No. 373,597, dated November22, 1887.

Application filed July 6, 1887. Serial No. 243,498. (No model.)

To all whom it may concern:

Be it known that I, ALBERT CLIFTON Mo- MICKEN, of NVinnipeg, in theProvince of Manitoba and Dominion of Canada, have invented a new andImproved Combined Discount-Measuring Glass and Bank-Note Examiner, ofwhich the following is a full, clear, and exact description.

This invention relates to a combination implement that is applicable foruse in examining and in'redeemiug bank-notes; and it consists,essentially, of an oblong glass of any desirable thickness, square atone end and semicircular at the other, and provided along the edges forthe full length of a bank-note with a scale that is marked, etched, orotherwise applied, said scale appearing, preferably, in inches and partsof an inch, and being used for measuring notes and parts of a note, andin ascertaining the exact size and length of signatures and numberingfor comparison with the known size of lettering, numbering, andsignatures of genuine bills. Along the edge of the semicircular end isalso marked or etched a measure or scale adapted to measure parts ofcircles, vignettes, curves, die. Just within the semicircle at one endof the glass there is mounted a magnifying-lens of sufficient power toexpose the degrees of fineness or coarseness of the fiber of the paperon which the notes are printed, and also to expose any inaccuracies inthe vignette, pattern, printing, lathe, and'scroll-work. On the rim ofthe setting containing .the magnifyinglens there is also marked a scaleor measure for convenience in measuring circular parts of vignettes andparts of bills undergoing examination by the magnifier. Upon the mainbody of the glass there is marked arectangular oblong ligure which isthe exact size of a bank-note, and this ligure is subdivided into fifthsand tenths, so that the approximate portion lost from a note may bequickly ascertained upon the presentation of the note.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar gures of reference indicatecorresponding parts in all the views.

Figure 1 is a face view of my combined measure and discount glass. Fig.2 is a crosssectional View, taken on line2 2 ot'lig. 1; and

Fig. 3 is a View of the device as it appears when in its case.

In the drawings, 10 represents a glass plate the edges of which aregraduated to inches, asshown at 11,this graduation extending along theparallel edges and across one end of the glass, which said end is atright angles to the said parallel edges. The other end ot' the glass isin the form of a circle, 12, which is also graduated, as shown at 13,said graduation being employed for the purpose hereinbefore referred to.Just within the semicircular end the glass l0 is apertured, and in theaperture so formed there is fitted a gasket, 14, which serves as thesupport for a sleeve, 15, which carries a lens, 16, the upper rim, 17,of the sleeve 15 being graduated as indicated. The rectangular end ofthe plate 1() is divided by a central longitudinal line, a, that is theexact length of the bank note or bill in connection with which thedevice is to be employed, and this line is divided into live equallengths by cross-lines b, thus dividing that portion ofthe face of theplate over which the line a. passes into ten equal portions.

In operation the glass is to be placed upon the note to be examined andthe note is to be evenly covered by that portion of the glass that istraversed by the line a and divided into tenths, as described. Then by acasual glance the amount missing from the bill can be quicklyascertained. When the glass is to be used to ascertain the length ofsignatures and the size ofletteriug and numbering, in order to compareWith the size of signatures, letters, and numbers otbills known to begenuine, the glass may be used in much the same manner as the ordinaryfoot-rule. For very line measuring the scale 13 is employed, beingsubdivided to sixteenths instead of to eighths, as is the case with thescale 11. In examining a suspicious bill or note with the lens 16 theglass 10 is grasped and the lens is properly focused.

By rounding one end of themcasure I not only obtain a circular measurefor the purpose of measuring vignettes and so on, but I guard againstliability of breaking the rectangular cor11ers,and at the same timeincrease the facility with which the glass may be inserted and removedfrom its case, such a case as I prefer to employ being shown in Fig. 3.-

IOO

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. A combineddiscountmeasurer and bank-- note examiner consisting of a glass platehaving an oblong figure of the exact size of a banknote 4marked thereon,the said figure being divided into rectangular spaces, substantially asdescribed. v

2. A combined discount-measurer and banknote examiner consisting of anoblong glass plate square at one end and semicircular Aat the other andprovided with scales along its edges and with an oblong figure of theexact bank-note, the said figure being divided into rectangular spaces,as set forth.
